but they are not co-oriented. In fact, the angle spread of theirc-axes within a rod is typically 30° and occasionally up to 60° or even 90°, as shown in the PIC map of human enamel from a young adult molar, in the inner enamel region, presented in Fig.1. For example,...
of a three-dimensional organopolysiloxane {preferably an organopolysiloxane of the formula (R is a monovalent hydrocarbon; (a) to (d) each is a molar fraction of a siloxane unit and (a) is 0.1-0.6; (b) is 0-0.45; (c) is 0-0.3; (d) is 0.3-0.8, with the proviso that (a)/(...
Self-templating assemblies of the human prion protein are clinically associated with transmissible spongiform encephalopathies. Here we present the cryo-EM structure of a denaturant- and protease-resistant fibril formed in vitro spontaneously by a 9.7-kD
The molar-based distribution indicated that all the comprised two molecular species differing in molecular size, although the weight-based distribution showed a single species. A comparison of molecular structures of buckwheat starches to cereal starches indicated buckwheat had a larger amount of LC, ...
Molar tooth structure (MTS) represented by complex ptygmatical shapes is widely distributed in the Proterozoic of the world. MTS filled by fine, equant sparry calcite (or dolomite) displays an abrupt contact with hosting rocks, which are mainly composed of carbonaceous micrites and fine-grained ...
Protein concentration was determined by measuringA 280 (15) using a molar extinction coefficient of 93,600 m−1 cm−1. Assays used to measure Man26A activity against 2,4-dinitrophenyl-β-mannobioside (2,4-DNPM2), carob galactomannan, and azo-carob galactomannan were as described ...
In this communication, the coordination numbers of liquid metals can be predicted by the modified coordination equation with their atomic parameters, molar... PT Dong - 《Metallurgical & Materials Transactions A》 被引量: 65发表: 2005年 Measurement of Densities and Estimation of Critical Properties ...
Modeling the temperature dependence of the critical shear rate as an activation process yields activation energies ranging from 12 to 39 kT for different surfactant to salt molar ratios. There is no clear relationship between the activation energy and the surfactant to salt molar ratio. 展开 ...
1a), and incubated it with increasing amounts of recombinant Elongin. We started transcription by addition of CTP, UTP and GTP at final concentrations of 10 µM. A clear stimulation of RNA synthesis was observed when Elongin was added in a 1:1 molar ratio to Pol II (Extended Data ...
Firstly, high purity ingredients (99.999%) were weighed at molar ratio and melted in the crucible at 1050 °C for 12 h, and then stirred for 12 h. The homogenized solution at high temperatures was cooled to be used as an oversaturated solution. The surface-cleaned substrate GGG would ...
